Artificial Armesis Essay

Prosthesis is a term used for replacing a human body part which has been damaged or cut accidently with an artificial one. Earliest users of prosthesis were Ancient Egyptians. Due to war injuries they used prosthetic limbs to look complete. A prosthetic toe was found on a 3000 years old mummy. An ancient Greek historian

Many veterans are missing major limbs, and are very handicapped making work and everyday life a huge struggle. There are prosthetic legs and arms that can be used, but they often take a long time to learn, and are very costly. In a recent interview with NBC News, a veteran by the name of Mike Kacer explains how the government spent $117,000 providing him with prosthetic arms over the last five years, and he doesn’t even like to use them. "I could actually tie the shoe faster without the prosthesis," Kacer says, and he’s not the only one that feels this way. Many other veterans using these prosthetic limbs eventually abandon them due to painful, unreliable and hard to use reasons. “Of the roughly 1,600 veterans who have suffered major limb losses from the wars in Iraq and Afghanistan, about 319 have faced amputations of some part of their arms.” (NBC News). Not only is that a lot of money spent on prosthetics that are hard to use, painful, and eventually abandoned, arms rather than legs are a lot harder to use according to research by Gary Berke, a Stanford University instructor who operates a private clinic providing prosthetics. "Walking is relatively straightforward," Berke said. Artificial legs essentially can do everything that real ones do. Artificial arms, however, are not nearly as adept as the real ones. "We're behind the eight ball in terms of

Prosthetics has always been part of most of our history, and it has come a long way since then. Forms of prosthetics date way back to the Civil War, and has made a lot of progress throughout the years. During the Civil War, many soldiers would have to be amputated everyday to save their lives. For example, in the text “I Will Not Get Out of Heart Yet,” it states that “Soldiers shot in the arm or leg on the battlefield were highly likely to develop potentially fatal infections, and the only way to prevent a painful death was to cut off the damaged body part.” Despite this fact, prosthetics were extremely uncomfortable to wear and were considered “crude contraptions” and “ were usually made of wood or steel --- that were awkward and painful to wear.” Many soldiers did not like having prosthetic limbs, as they were uncomfortable to wear and awkward to move around with.

Certain substances trick the body into thriving. For example, it was thought that the body rejects all foreign substances. If you get an implant of steel, or other metal, into your body, the body will coat the invasive object in collagen, and the object will slip free. Since the body cannot determine between harmful and beneficial foreign matter, months after implantation, the new appliance would slip free. However, titanium decieves the body into incorporating it naturally into its systems. It triggers no immune response, and bones will begin to grow around it, as if it was always there. Thus, titanium is used for replacement joints, and much more.

A major impetus to improving artificial limbs started when the United States encouraged companies to improve prosthetics instead of munitions (Norton, 2007). The combination of lighter materials and robotics assist has created huge advancements in functionality and has dramatically improved quality of life and potential for independent living. Even with the advancement of these limbs, the basic mechanical principals are still the same. Modern times allow for many different types of limbs to be created. Limbs can be created to match skin tone, freckles and fingerprints. There are three many ways a limb can be made to move. The first is attaching the limb to a moving body part to act as a gear shifter. Another variation is a motor attached and the person can switch modes by a mechanical toggle shift. The most advanced movement is the myoelectric capability. This is when electrodes are placed on the muscles of the residual limb. When contracted the arm will move according to which electrode fired. A microprocessor can also be attached to learn exactly how the person walks (Clements, 2008). Modern prosthetics offer valuable life skills, yet are very

Aimee Mullan was disabled from the knee down. With that knee still workable having a prosthetic leg that could move was an option. This information shows how her disablement wasn’t the end of the world for her. On the other hand, Bethany Hamilton’s whole arm was bitten off. She tried a prosthetic arm, but it couldn’t move without her elbow, so it was just for show.

On 8/9/17 I met Mr. Malone at Bremmer Prosthetics regarding his Myoelectric arm. The mechanical arm was checked out and a couple of screws were changed and some strap replacement was done. Nate the technician did some testing on the muscle of the arm to make sure he would be able to operate the myoelectrical arm. There are 5 functions to the hand in regards to gripping. Mr. Malone last had an electric arm 17 years ago. The technology has advanced. The testing showed that Mr. Malone would be able to operate the new mechanical arm well. We were told he would need to have some occupational therapy once he had the new arm. I asked what the projections for the mechanical arm are and was told about 5 years. The mechanical arm is about 10 years

Modern prosthetic limbs have become very advanced in the last decade. They now have the ability to grip objects, have running limbs, and many more wonderful things. Although these prosthetics are great, they are lacking some key extras that amputees would relish. What amputees really want is their sense of feeling back. They want to reach out with their prosthetic limb and be able to tell if the stove is on or off. They want to be able to press the gas of an automobile. This sense, that all non-amputees take for granted, would be a great place to start the improvement of the perfect prosthetic limb. To accomplish such a daunting task, engineers must figure out an alternative source that could interact with the amputees still intact nerve endings. This way they can use their still functioning nerves to communicate with their pseudo-nerve and have the ability to move their prosthesis around with complete control of it and its sense of touch. I believe this has not

Lately there have been more and more smart machines that have been taking over regular human tasks but as it grows the bigger picture is that robots will take over a lot of tasks now done by people. But, many people think that there are important ethical and moral issues that have to be dealt with this. Sooner or later there is going to be a robot that will interact in a humane manner but there are many questions to be asked like; how will they interact with us? Do we really want machines that are independent, self-directed, and has affect and emotion? I think we do, because they can provide many benefits. Obviously, as with all technologies, there are dangers as well. We need to ensure that people always

Internal fixation devices in the past had been made of stainless steel or titanium, but with problems resulting from those permanent devices, an innovative approach is being considered. Bioresorbable implants are a possible replacement to the original implants that would eliminate the need for removal, which has shown to be a problem for traditional implants.

In addition, the wires will need to conduct electrical signals received from the microphone and processor/stimulator and be flexible enough to allow navigating to and from their desired destinations. To accomplish this, a conductive material with a biocompatible coating is likely to be the most feasible approach. Currently, the wires in cochlear implants are composed of platinum conductive wires coated with silicone and this approach is used for good reason. Silicone, as previously stated, has outstanding biocompatibility, flexibility, stability, softness, water-tightness, resistance to corrosion, and acts as an insulator from electrical stimulus. While platinum is used as the conductive material because it has low chemical reactivity, is highly corrosion resistant, biocompatible, flexible, and does not display stimulus-induced corrosion resistance like most other conductive metals, meaning it should last the lifetime of the patient. These properties simply make it the greatest available conductive material for this application, and by coating it in silicone you remove any potential unwanted exposure to the surrounding

In prescription, prosthetic limb is a fake gadget that replaces a missing body part. The procedure of making this known as appendage prosthesis. It is a piece of the field of bio mechatronics, the study of utilizing mechanical gadgets with human muscle, skeleton, and sensory systems to support or improve engine control lost by trauma, ailment, or deformity. Prostheses are ordinarily used to supplant parts lost by harm (traumatic) or absent from conception (intrinsic) or to supplement imperfect body parts. Inside the body, manufactured heart valves are in like manner utilization with simulated hearts and lungs seeing less normal utilization. Other therapeutic gadgets and supports that could be considered prosthetics incorporate amplifiers,

This inspires groups to donate 3D-printed prosthetic limbs to amputees who have limited resources. Cost is a major factor for many families who have children that require new prosthetics as the child grows.

Bio-materials have lots of uses in the field of medicine. They can be used for purposes as simple as a stent in cardiovascular surgery or as complex as a pacemaker or
